Letters Patent No. 93,324, dated August 3, 1869.

IMPROVEMENT IN Doon-LATCHES.

The Schedule referred to in these Letters Patent and making 'part of the-same To all whom it may concern My invention relates to a latch for doors, dto.; andconsists in a peculiar' form of handle, and a novel connection between the same and the .latch-bolt.

In the plate of drawings which illustrate my invention- Figure I is a horizontal section through a portion of door, with my invention applied thereto.

Figure vII is an inside view of the casing' in which the latch-bolt is arranged to move.

A is the handle, cylindrical in form, and made of any substance which it may be deemed desirable to use.

C is the lever-bar, made solid with the said handle A, or attached to the same in any other manner which I deem desirable.

The axis of the said lever is at right angles with the axis'of the said handle.

B is the rosette, secured by screws, or otherwise, to the door.

The lever c is pivoted to the rosette by means of the pin H', which passes through circular holes cnt-in the said rosette,'and also through holes out in the lever c.

The. latch-bolt Ill terminates with the horns I) D, v

which fit respectively over the ends of the said levers C C.

The said latch-bolt is arranged Within the tube or casing E to move out and in through the plate K, which is made solid with the said tube E.

His a spiral spring, which causes the said latch-bolt to recoil, and assume its normal position after being actuated by the said levers.

The operation of my invention is readily seen.

The levers C, being actuated by the hand applied to the handle A, describe the arc of a circle about the pivot H as a centre, and press upon the horns D of the bolt F, thereby throwing back the said bolt 'within the casing E, and releasing' the door, and when the pressure is released from thc handle, the spring H throws the bolt back to its normal condition.

It will be observed that the levers'aet independently bolts, somewhat similar to those herein described, have been heretofore patented. I therefore 'do not cla-im the "same severally and broadly.

I claim, and `desire Ato secure by Letters Patent- The arrangement and combination of the handles A and levers C, (pivoted respectively to the rosettes B,) with the horns D of the latch-bolt, substantially as described.

EMMONS MAN LEY.
